The application discloses a method for determining human bocavirus type I / II based on HNB-LAMP and CRISPR / Cas12a-AuNP double colorimetric signals, and belongs to the technical field of in vitro molecular diagnosis. The application first performs isothermal amplification on a human bocavirus NP1 gene in a single tube by using HNB-LAMP technology, realizes one-step visual preliminary screening through color change (purple to blue) of hydroxynaphthol blue (HNB), then adds a CRISPR / Cas12a-AuNP typing system to positive amplification products, utilizes trans-cleavage of HT44 hairpin transduction structure after Cas12a is activated by specific amplicons, releases RNA cross-linking agent, and then causes aggregation and precipitation of DNA functionalized gold nanoparticles (AuNPs), to produce visible purple precipitate. The application realizes accurate typing detection of human bocavirus type I / II through double colorimetric signals (blue solution + purple precipitate), does not need complex instruments, is simple and easy to operate, has high sensitivity and strong specificity, and is suitable for primary medical units and on-site rapid screening.

The application provides an adjustable ergonomic lower limb pad, and belongs to the field of medical care, which comprises a shell, an adjusting mechanism, a telescopic square tube, an adjusting block, a closing block, and a support leg. The adjusting mechanism is arranged on the inner side of the shell. The telescopic square tube is arranged in the shell. The adjusting block is slidably connected to the inner side of the shell. The closing block is arranged on the outer side of the adjusting block. The support leg is slidably connected to the inner side of the bottom of the adjusting block and the closing block. After the magnetic steel and the iron sheet are magnetically locked, the heightening support block is pushed to be attached to the shell, so that gaps after adjustment are avoided. The components cooperatively constitute a modular mechanical structure, which has the functions of telescopic adjustment, magnetic locking and flexible support, meets the medical care demand, takes into account the ergonomic comfort and the safety and stability of the equipment, thereby realizing overall light weight through a simple structure, reducing the manufacturing cost, and further reducing the use cost of medical units.
